[Feature Request] Add option to create individual notes for each column (stack)

## Summary
I’d like to request a feature that allows creating a Joplin note from an entire column (stack) in a Kanban board.

## Use Case
In my personal workflow, I use columns as days of the week — Monday, Tuesday, Wednesday, etc.
Each card under a column represents a task or log entry for that day.
It would be very helpful to generate a single note for the entire column at the end of the day, for example:

- Title of the note: "Wednesday"
- Contents: All cards listed as markdown bullets

This would help me keep daily journals or logs based on Kanban activity, using Joplin’s regular note structure.

## Why This Matters
- Helps with archiving daily logs
- Allows further annotation or tagging using Joplin's note features
- Maintains a record of completed tasks in a readable format

## Proposed Feature
- Add a context menu (⋮) option on the column to "Create note from column"
- The generated note should:
- Use the column title as the note title
- List all card titles and optional descriptions under that column

The issue names no files or tests. Start at the Kanban column context menu and trace how column cards, titles, and optional descriptions are represented. Done means a column action creates one note titled with the column name and lists its cards as markdown bullets.
